Live Tile Image rendering Technique

Question

Hello,

I'm trying to render an image from an image Url  (say of 320X200) dimension image to 100X100 box. and  hence used the below code.

//is the converter snippet that converts image url

BitmapImage bImg = new BitmapImage(new Uri(ImageUrl, UriKind.RelativeOrAbsolute));
                   

                    bImg.DecodePixelHeight = 100;
                    bImg.DecodePixelWidth = 100;
                    return bImg;



This Bit map image is bound as source to image tag 

<Image Source="{Binding ImageUrl, Converter={StaticResource NewsImgConverter}}"  Stretch="Uniform" Width="100" Height="100" VerticalAlignment="Top" HorizontalAlignment="Center" Margin="0,0,0,0"/>

and the same image Url is directly given to display on Live Tile.

I see that the clarity or visibility of image rendered on Live tile is better than what is rendered in the App.

What should I do to get the clarity as that of Live Tile(Square rendering)

Any other additional steps to be do
